Analysis of results • a = g(m – uM) / (M + m) • This will give + acceleration (down and to the right) if m > uM, and a = 0 if m = uM. • The function is undefined if m < uM since negative a makes no physical sense; it will never fall “up” and to the left. The reality is a will stay at zero if a≤ 0. ...
